openDVS v0.1.0-alpha.3

openDVS v0.1.0-alpha.3 — two decks, robustness, and field tooling

The DJ-rig release: two turntables drive two decks, plus the hardening
and setup tooling that make a real rig practical.

New

• Two-deck playback — odvs play deckA.flac deckB.flac: deck A on
  interface inputs/outputs 1/2, deck B on 3/4, out to your mixer. The
  classic 2× turntable + 4-in/4-out interface + analog mixer rig, from
  the CLI. Graceful fallback on 2-channel devices.
• odvs calibrate — measures live deck wiring and fixes it: reversed
  direction (miswired cartridge leads), dead/mono channels, level; writes
  the config. Calibration now applies on every live path.
• odvs capture — guided corpus recording (steady / pitch / scratch /
  back-cue / needle-drops / noise-floor), one WAV per phase + metadata.
  This is how decoding commercial timecode records gets built.
• AppImage downloads for Linux (x86_64 + aarch64), alongside
  tarball / .deb / .rpm. chmod +x and run; ./openDVS.AppImage cli …
  for the command line.

Hardening

• Nightly 4-hour soak (two noise seeds) asserting lock retention,
  ≤2 ms position accuracy, relock time, and bit-error rate — the
  "professional bar" (zero dropouts over a long set) now enforced in CI.
• Decoder fuzzing (cargo-fuzz): arbitrary input never panics and
  never yields non-finite telemetry on the audio path.
• cargo deny on every PR: dependency licences audited for GPLv3
  compatibility, security advisories checked.
• Linux artifacts stripped (~50 MB → ~10 MB).

Choosing a download

You run	Grab
Linux (any)	…-x86_64.AppImage (portable)
Ubuntu/Debian	odvs_*_amd64.deb (arm64 for Pi)
Fedora	odvs-*.x86_64.rpm
Arch	packaging/arch/PKGBUILD
macOS (M-series)	…-aarch64-apple-darwin.tar.gz
macOS (Intel)	…-x86_64-apple-darwin.tar.gz
Windows	…-x86_64-pc-windows-msvc.zip

macOS/Windows builds compile in CI but have not been run on those
platforms yet — smoke-test reports welcome. macOS is unsigned
(right-click → Open). Full detail: CHANGELOG.md.
